Recently acquired Yankees starter J.A. Happ has contracted hand, foot and mouth disease — also known as coxsackie — Brian Cashman told reporters Tuesday, ahead of the Yankees’ game against the Orioles. The lefthander will “probably” be able to start in Boston.

This is the same illness, common among children, that sent Mets ace Noah Syndergaard to the 10-day disabled list on July 23 after a start at Yankee Stadium. The team believed Syndergaard contracted the virus at a youth camp.

The hurler went to NY Presbyterian on Tuesday afternoon and then was sent home. Cashman said he does not know how Happ, who made his Yankee debut Sunday, contracted the disease. The Yankees were bringing in extra hand sanitizer to try and prevent it from spreading through the clubhouse.

“We’ll continue to monitor the patient and let the virus take its course, so he’s still scheduled to start and it’s not something that right now that is in jeopardy, as of yet,” Cashman said of Happ taking the mound Saturday at Fenway, during a crucial four-game series with the AL East-leading Red Sox.

But the team is taking precautions to be prepared in case Happ cannot take the mound. Luis Cessa was limited to one inning in a start for Triple-A on Tuesday night in case the Yankees needed him to step in.

Also, Lance Lynn, whom the Yankees acquired Monday night from the Twins, was expected to arrive Tuesday night and is stretched out and would also be available.

Boston will definitely be down an ace during the series, announcing Tuesday that Chris Sale was placed on the 10-day disabled list with mild left shoulder inflammation, retroactive to July 28. He will miss his Thursday start, with righthander Brian Johnson taking his place.
